This workstation integrates multiple handling robots, welding robots, fixtures, and positioners, featuring a simple layout and rational configuration. It is primarily designed for welding seams on traction cross frames, plate pins, and assembly modules, with a welding qualification rate of 95% and no common quality issues. Anti-deformation functions are incorporated into relevant welding positions. The robots can automatically complete operations such as part transportation, process transfer, and finished product stacking—manual intervention is only required for placing material racks, with no further human involvement needed.
